Built-in motion detectors for indoor installation
A motion detector ensures safety and energy saving in your home.
When purchasing, pay attention to the size of the detection zone and the direction of the sensor, so that all desired areas fall within the field of view of the motion detector.
Most sensors use infrared technology. Also called PIR sensor
Infrared motion sensors detect changes in an infrared field.
A motion detector uses a PIR which responds to rapid temperature changes, the presence of a person (heat source) within the monitored room will be signaled immediately by the detector. This so-called PIR sensor is sensitive to the wavelength of IR light that is detected by the detector. human body is being broadcast.
Ultrasonic sensors operate on sound waves that are not perceptible to the human ear
